# About
This is a [tinkerbell](https://github.com/tinkerbell) on [k3s](https://github.com/k3s-io/k3s) kubernetes cluster playground wrapped in a Vagrant environment.
# Usage
Configure the host machine `hosts` file with:
```
10.11.0.4 registry.example.test
10.11.0.10 s.example.test
10.11.0.50 traefik.example.test
10.11.0.50 kubernetes-dashboard.example.test
```
Install the base [Debian 11 (Bullseye) vagrant box](https://github.com/rgl/debian-vagrant).
Optionally, connect the environment to the physical network through the host `br-lan` bridge. The environment assumes that the host bridge was configured as:
```bash
sudo -i
# review the configuration in the files at /etc/netplan and replace them all
# with a single configuration file:
ls -laF /etc/netplan
upstream_interface=eth0
upstream_mac=$(ip link show $upstream_interface | perl -ne '/ether ([^ ]+)/ && print $1')
cat >/etc/netplan/00-config.yaml < 50061/TCP 25h
# tink-server ClusterIP 10.13.186.115 42113/TCP 25h
# boots LoadBalancer 10.13.65.159 10.11.0.60 80:32001/TCP,514:31255/UDP,67:30362/UDP,69:30225/UDP 25h
# tink-stack LoadBalancer 10.13.226.115 10.11.0.61 50061:31034/TCP,42113:31407/TCP,8080:31947/TCP 25h

```
## Traefik Dashboard
Access the Traefik Dashboard at:
https://traefik.example.test/dashboard/
## Rancher Server
Access the Rancher Server at:
https://s.example.test:6443
**NB** This is a proxy to the k8s API server (which is running in port 6444).
**NB** You must use the client certificate that is inside the `tmp/admin.conf`,
`tmp/*.pem`, or `/etc/rancher/k3s/k3s.yaml` (inside the `s1` machine) file.
Access the rancher server using the client certificate with httpie:
```bash
http \
--verify tmp/default-ca-crt.pem \
--cert tmp/default-crt.pem \
--cert-key tmp/default-key.pem \
https://s.example.test:6443
```
Or with curl:
```bash
curl \
--cacert tmp/default-ca-crt.pem \
--cert tmp/default-crt.pem \
--key tmp/default-key.pem \
https://s.example.test:6443
```
## Kubernetes Dashboard
Access the Kubernetes Dashboard at:
https://kubernetes-dashboard.example.test
Then select `Token` and use the contents of `tmp/admin-token.txt` as the token.
You can also launch the kubernetes API server proxy in background:
```bash
export KUBECONFIG=$PWD/tmp/admin.conf
kubectl proxy &
```
And access the kubernetes dashboard at:
http://localhost:8001/api/v1/namespaces/kubernetes-dashboard/services/https:kubernetes-dashboard:/proxy/
## K9s Dashboard
The [K9s](https://github.com/derailed/k9s) console UI dashboard is also
installed in the server node. You can access it by running:
```bash
vagrant ssh s1
sudo su -l
k9s
```
# Notes
* k3s has a custom k8s authenticator module that does user authentication from `/var/lib/rancher/k3s/server/cred/passwd`.
